Definitions

  • the invention relates to a method and an apparatus for producing a Nonwoven fabric having a pile producer and a nonwoven fabric layer formed from one of the pile fabricator continuously discharged single or multi-ply card web a nonwoven web with a generated over the laying width variable thickness.
  • Method and device of this type are known from DE 43 04 988 C1. They have to the goal, in the laid nonwoven web a transverse to the nonwoven web direction thickness profile to produce, which is lower in the edge areas than in the middle. The reason for that is that when solidifying the nonwoven web in a needle machine, the nonwoven web through the Needling process inserts laterally, i. becomes narrower, at the same time the thickness profile changed. From a needle machine fed nonwoven web of uniform thickness The needle machine produces a felt web which is thicker in its edge regions than in the middle is. To eliminate this unevenness, the needle machine is fed with a nonwoven web to, in their thickness from the center, starting in the direction of their edge areas accordingly gets thinner.
  • an apparatus for producing a nonwoven fabric comprising a card that makes a carded web, and a fleece layer.
  • the fleece layer has one Set of bandages for receiving the card web and a movable laying carriage that transversely is movable above a drawstring and fed from the Legebändem card web zigzagging and overlapping on the drawstring. Because of the movement of the Legewagens is in the fleece layer also a so-called. Uppercarriage available, the changes compensated for the run length of the held by the ribbon tapes.
  • a pile store which serves, Florüberschuß when the take-up speed of the nonwoven layer is less than the delivery speed of the card is to give off and Florüberschuss when the take-up speed of the battlegder greater than the delivery speed of the carding is.
  • From DE 22 59 919 A is an apparatus for warping confused, cross or longitudinal Nonwoven fabrics known consisting of pairs of rolls or Walzentrios, in which the distance between the pairs of rolls or Walzentrios smaller than the diameter the rollers is, whereby the clamping point of the pair of rollers to pair of rollers are made small can.
  • the warping of random, cross or longitudinal fiber webs has the goal the stretching properties of a felt produced therefrom in the different stretching directions to match each other.
  • the invention is based on the object, a method of the type mentioned and specify a device suitable for the execution of the same, the storage of a Nonwoven web allow desired cross-sectional profile.
  • the invention provides a method whose features in the claim 1 are included.
  • Alternative embodiments of the same inventive concept spring are objects of claims 2 and 3.
  • Two devices to solve The object set are described in claims 11 and 12.
  • Advantageous developments The invention are the subject of the respective dependent claims.
  • the invention thus provides, between the production of the pile and the transfer of the card web to the nonwoven a stretching operation at a defined point of the transport path of the Florbahn, so in practical execution in a separate drafting, which is not only the production of thick and thin places in the card web in predetermined
  • Rapport has, but it also allows both adjacent to the drafting system To run aggregates at constant speeds.
  • the Velocity modulation which generates the cyclic drafting system in the card web, by buffering means opposite the adjacent aggregates buffered.
  • the intake side roller in the drafting system at a constant speed accordingly the constant discharge speed of the pile generator rotates and the cyclic stretching by cyclically accelerating and decelerating the rotational speed of the Outflow side roller of the drafting system is a buffer on the discharge side provided the drafting, which cyclically variable a portion of the card web Length absorbs.
  • a buffer be dispensed with if the adjacent to the drafting units with The same speeds are driven, as their respective adjacent rolls of the drafting system. This then requires a corresponding modulation of the delivery rate the carding or take-up speed of the nonwoven layer.
  • the laying carriage of a fleece layer leads across the laying belt on which the nonwoven web travels generated by depositing the pile, running, reciprocating motion.
  • the reversal of the movement at the end of the movement path takes place not abrupt, but has forced braking and acceleration phases. If now the card web is fed at a constant speed, resulting due these deceleration and acceleration phases thickening in the deposited nonwoven web at exactly those places where the nonwoven web should actually be thinner. Therefore are known fleece layers constructed so that the laying carriage a variable Flortransport nie has, which makes the use of a cache necessary to the uniform pile take-up speed of the feed belt of the nonwoven fabric nonuniform To match the pile transport speed of his laying trolley.
  • the laying carriage can be adapted to a buffer in the nonwoven be waived.
  • the necessary temporary storage takes over according to this Embodiment of the invention existing between the drafting and the nonwoven Latch, which is for the compensation of the cyclically variable delivery speed the drafting system is necessary anyway.
  • the drafting system can be multi-level, with a choice between each step each buffer may be arranged, which allow a relaxation of the pile fibers, which is advantageous in some applications.
  • the work result is measured and, based on this, a feedback control of the drafting system is performed.
  • the Nonwoven web thickness detected transversely to the longitudinal extent of the nonwoven web for example with the help radiometric, acoustic, optical or mechanical measuring devices, and the output signals These measuring devices are used to influence the extent of travel and Length of stretching zones used within the card web.
  • the drawings show on the right side the tambour 1 of a card, from which two transfer belts 2a and 2b to a two disc rollers drafting system 3 extend, downstream of which the first intermediate band 10 of a pile memory 4 connects, which leads to the feed belt of a webbed 5.
  • the drive devices (Engines) for carded roll, taker, deduction, drafting system, storage tank and Nonwoven layers are not shown here for reasons of clarity.
  • the Drawframe 3 consists of a pair of disk rolls 8a and 8b, each consisting of a Variety of mutually parallel discs, the axes 9a and 9b of the disc rollers 8a and 8b have a distance from each other which is smaller than the sum of the Radii of the discs.
  • the disks of the disk rollers 8a and 8b are each "gap" provided, i. the discs of a disc roller engage in the disc spaces the other disk roll in, so that the disk rolls 8a and 8b mutually penetrate. This measure makes it possible to make the draw zone short.
  • the mutual center distance of the disk rollers 8a and 8b is preferably adjustable, the length of the draw zone to the properties of the respective processed pile material, in particular the staple length of the pile fibers, adapt.
  • Part of the drafting system 3 are also the disk rollers 8a and 8b opposite Documents that in the example of FIG. 1 of the lower transfer conveyor 2b and the first intermediate band 10 of the storage tank 4 are formed. Both bands have a possible non-slip surface, so between the disk rollers 8a and 8b and the documents formed by the bands 10 and 2b have sufficient friction, in that due to a peripheral speed difference between the peripheral speeds the disk rolls 8a and 8b of the web between the disk rolls 8a and 8b can be longitudinally stretched.
  • Disk wheels are preferable because they have another advantage, namely the already mentioned that the distance between the nip lines, each from a disk roll and its counterpart is formed, as far as possible can be reduced. This distance between the nip lines determines the length the draw zone, which in turn depends on the fiber length in the pile and the fiber orientation should be chosen. Therefore, the distance between the axes of the two Disk rollers 8a and 8b also preferably adjustable.
  • the draw zone is to be very short, rolls must be correspondingly small in diameter be selected so that the distance between the aforementioned clamping lines is small. In this case, it may be necessary for reasons of stability, the rollers at several To support their longitudinal extension at their side facing away from the drafting rollers.
  • the guide roller on the draw roller To support the opposite side at several of its longitudinal extension to a bending to prevent.
  • Fig. 2 shows a construction in which each pad of a rotating screen belt 14th is formed, which runs over a support structure 15, which in the area of the associated Stretching roller 8a and 8b has a deflection small curvature radius'.
  • Support structure 15 is at least in the region of the draw roll opposite Support surface of several parallel juxtaposed ribs, the between form interspaces, or she has there a vented to the outside perforation on, in which when entering the gap between draw roller and pad from the Flor pushed out air can escape through the screen belt.
  • FIG. 3 An alternative to this is shown in FIG. 3, according to which the pile conveyor belt 2 b and the intermediate belt 10 in the region of the drafting rollers shown here with a relatively small diameter 8b and 8a respectively over deflection edges 16 small radius of curvature ', comparable to Embodiment of FIG. 2, are performed.

  • the storage roll 11 is along the first intermediate belt 10 and the second intermediate belt 12 movable.
  • the variable caching of the stretched Card web is necessary to cycle in times in which the outgoing disk roll 8a of the drafting system 3 runs faster than in the other times to absorb the card web and to prevent them from being compressed in front of the feeding belt 13 of the nonwoven layer 5.
  • the pile storage 4 can be arranged on the intake side to the drafting system 3, namely then, when the stretching operation at a constant rotational speed of the drain side Disk roller 8a of the drafting system 3 by cyclically braking the disk roller 8b is performed and in this case a compression of the discharged from the carding drum 1 Florbahn before the drafting 3 must be prevented.
  • FIG. 1 of the device passes through the two-ply card web delivered by the carding drum 1 the drafting system 3.
  • the air contained in the card web is compressed by the compression the carded web is pushed out of this as far as possible, taking in the interstices between the discs of the drafting rollers and possibly through the pad escapes.

  • the upper run of the second intermediate belt 12 gives the card web to the feed belt 13 of the batt 5 from.
  • the tuning of the cyclic acceleration of the draw roll 8a and the first intermediate belt 10 with the laying motion of the fleece layer takes into account the length of the Running path of the card web between the drafting 3 and the delivery point of the batt and is set up in such a way that thin points generated by the drafting system in the card web in the Edge area of the nonwoven web produced from the card web are stored.
  • the speed with which the card web is received by the nonwoven layer 5 is constant, but larger than the constant speed according to the amount of stretch of the card web, with which the card web enters the drafting system 3.
